DNP3 TCP/IP link mode is supported by the protection relay.
The protection relay listens for a connection from a DNP3 client on port specified by the user. Default values for TCP port number range from 20000...20004 depending on instance number. A different port can be selected with the TCP Port parameter.
DNP3 TCP/IP link mode and UDP broadcast are supported by the protection relay. UDP broadcast requires that there is an active TCP connection by the client.
Documentation on DNP3 TCP/IP communication is available on www.dnp.org.
